Safety Information

Follow the guidelines in this section to ensure proper operation and safe use of the 1300 series.

FCC Safety Compliance Statement

FCC Compliance with its action in ET Docket 96-8, has adopted a safety standard for human exposure to RF electromagnetic energy emitted by FCC-certified eqipment. When used with approved Cisco Aironet antennas, Cisco Aironet products meet the uncontrolled environmental limits found in OET-65 and ANSI C95.1, 1991. Proper operation of this radio device according to the instructions in this publication results in user exposure substantially below the FCC recommended limits.

Safety Precautions

Warning Do not locate the antenna near overhead power lines or other electric light or power circuits, or where it can come into contact with such circuits. When installing the antenna, take extreme care not to come into contact with such circuits, as they may cause serious injury or death. For proper installation and grounding of the antenna, please refer to national and local codes (e.g. U.S.:NFPA 70, National Electrical Code, Article 810, in Canada: Canadian Electrical Code, Section 54).

Each year hundreds of people are killed or injured when attempting to install an antenna. In many of these cases, the victim was aware of the danger of electrocution, but did not take adequate steps to avoid the hazard.

For your safety, and to help you achieve a good installation, please read and follow these safety precautions. They may save your life!

1. If you are installing an antenna for the first time, for your own safety as well as others, seek professional assistance. Your Cisco sales representative can explain which mounting method to use for the size and type antenna you are about to install.

2. Select your installation site with safety, as well as performance in mind. Remember: electric power lines and phone lines look alike. For your safety, assume that any overhead line can kill you.

3. Call your electric power company. Tell them your plans and ask them to come look at your proposed installation. This is a small inconvenience considering your life is at stake.

4. Plan your installation carefully and completely before you begin. Successful raising of a mast or tower is largely a matter of coordination. Each person should be assigned to a specific task, and should know what to do and when to do it. One person should be in charge of the operation to issue instructions and watch for signs of trouble.

5. When installing your antenna, remember:

a. Do not use a metal ladder.

b. Do not work on a wet or windy day.

c. Do dress properly—shoes with rubber soles and heels, rubber gloves, long sleeved shirt or jacket.

6. If the assembly starts to drop, get away from it and let it fall. Remember, the antenna, mast, cable, and metal guy wires are all excellent conductors of electrical current. Even the slightest touch of any of these parts to a power line complete an electrical path through the antenna and the installer: you!

7. If any part of the antenna system should come in contact with a power line, don't touch it or try to remove it yourself. Call your local power company. They will remove it safely.

8. If an accident should occur with the power lines call for qualified emergency help immediately.

1300 Series Installation

•External antenna access point/bridge (with antenna connector for use with an external antenna)

Note To meet regulatory restrictions, the external antenna configuration and the external antenna must be professionally installed.

Note When installing the dual-coax cable, it is acceptable to unzip or pull the two cables apart at the ends if more separation is needed between the male F connectors.

Personnel installing the 1310 access point/bridge must understand wireless bridging techniques, antenna alignment and adjustment, and grounding methods. The integrated antenna configuration can be installed by an experienced IT professional.

Important Notes

This section describes important information about the access point.

Default Username and Password Are Cisco

When you open the 1300 series interface, you must enter a username and password. The default username for administrator login is Cisco, and the default password is Cisco. Both the username and password are case sensitive.

New Express Security Page Simplifies Security Setup

The new Express Security page in the 1300 series web-browser interface makes it easier to create SSIDs and assign security settings to them. Figure 1 shows the Express Security page.

Limitations of the Express Security page include:

•You cannot edit SSIDs. However, you can delete SSIDs and re-create them.

•You cannot assign SSIDs to specific radio interfaces. The SSIDs that you create are enabled on all radio interfaces. To assign SSIDs to specific radio interfaces, use the Security SSID Manager page.

•You cannot assign an SSID to a VLAN that is already configured on the access point. To assign an SSID to an existing VLAN, use the Security SSID Manager page.

•You cannot configure combinations of authentication types on the same SSID (such as MAC address authentication and EAP authentication). To configure combinations of authentication types, use the Security SSID Manager page.

Non-Cisco Aironet 802.11g Clients Might Require Firmware Upgrade

Some non-Cisco Aironet 802.11g client devices require a firmware upgrade before they can associate to the 802.11g radio in the 1310 access point/bridge when it is configured as an access point or workgroup bridge. If your non-Cisco Aironet 802.11g client device does not associate to the 1310 access point/bridge, download and install the latest client firmware from the manufacturer's website.

Throughput Option for 802.11g Radio Blocks Association by 802.11b Clients

When you configure the 802.11g 1300 series radio for best throughput, the 1310 access point/bridge sets all data rates to basic (required). This setting blocks association from 802.11b client devices. The best throughput option appears on the web-browser interface Radio0-802.11G Settings pages and in the speed CLI configuration interface command.

Use force-reload Option with archive download-sw Command

When you upgrade access point or bridge system software by entering the archive download-sw command on the CLI, you must use the force-reload option. If the access point or bridge does not reload the Flash after the upgrade, the pages in the web-browser interface might not reflect the upgrade. This example shows how to upgrade system software successfully using the archive download-sw command:

Radio MAC Address Appears in ACU

When a Cisco Aironet client device associates to an access point or bridge running IOS software, the device's MAC address that appears on the Status page in the Aironet Client Utility (ACU) is the MAC address for the access point or bridge radio. The MAC address for the access point or bridge's Ethernet port is printed on the label on the back of the access point or bridge.

Radio MAC Address Appears in 1310 Access Point/Bridge Event Log

When a client device roams from an access point (such as access point alpha) to another access point (access point bravo), a message appears in the event log on access point alpha stating that the client roamed to access point bravo. The MAC address that appears in the event message is the MAC address for the 1310 access point/bridge.

Mask Field on IP Filters Page Behaves the Same As in CLI

In Cisco IOS Release 12.2(8)JA and later, the mask that you enter in the Mask field on the IP Filters page in the 1310 access point/bridge GUI behaves the same way as a mask that you enter in the CLI. If you enter 255.255.255.255 as the mask, the 1310 access point/bridge accepts any IP address. If you enter 0.0.0.0, the 1310 access point/bridge looks for an exact match with the IP address that you entered in the IP Address field.

Repeater access points running Cisco IOS software cannot associate to parent access points that do not run IOS software (all 340 series access points, and 350 and 1200 series access points that have not been converted to IOS software).

Repeater Access Points Cannot Be Configured as WDS Access Points

Repeater access points do not support WDS. You cannot configure a repeater access point as a WDS access point, and if a root access point becomes a repeater in fallback mode, it cannot provide WDS.

A system software upgrade sometimes fails when you use Microsoft Internet Explorer version 5.01 SP2 to upgrade system software using the HTTP Upgrade page in the web-browser interface. Use a later version of Microsoft Internet Explorer to perform HTTP system software upgrades, or use TFTP to upgrade system software. Click this URL to browse to the Cisco 1300 Series Wireless Bridge Software Configuration Guide for complete instructions on performing software upgrades:

When Cipher is TKIP Only, Key Management Must Be Enabled

When you configure TKIP-only cipher encryption (not TKIP + WEP 128 or TKIP + WEP 40) on any radio interface or VLAN, every SSID on that radio or VLAN must be set to use WPA or CCKM key management. If you configure TKIP on a radio or VLAN but you do not configure key management on the SSIDs, client authentication fails on the SSIDs.

Enabling CKIP When in Bridge Mode

For higher throughput and enhanced security, Cisco recommends enabling CKIP when the 1310 access point/bridge is in the bridge mode.

Cisco CKM Supports Spectralink Phones

Cisco CKM (CCKM) key management is designed to support voice clients that require minimal roaming times. To date, CCKM supports only Spectralink Wireless Phones. Other voice clients have not been tested with CCKM and are not supported.

Non-Cisco Aironet Clients Sometimes Fail 802.1x Authentication

Some non-Cisco Aironet client adapters do not perform 802.1x authentication to the 1310 access point/bridge unless you configure Open authentication with EAP. To allow both Cisco Aironet clients using LEAP and non-Cisco Aironet clients using LEAP to associate using the same SSID, you might need to configure the SSID for both Network EAP authentication and Open authentication with EAP.

Limitation to PAgP Redundancy on Switches Connected by Bridge Links

When running PAgP on swtiched connected to 1310 seriess bridges, for ethernet traffic redundancy and load balance be aware that PAgP switchover takes at least 30 seconds, which is too slow to maintain certain traffic (for example, TCP) when switching from from port to the other.

There is no workaround for this limitation.

Caveats

This section lists open caveats in Cisco IOS Release 12.2(15)JA for the 1310 access point/bridge.

Open Caveats

These caveats are open in Cisco IOS Release 12.2(15)JA for the 1310 access point/bridge:

•CSCed66444—TKIP Michael MIC failure occurs in non-root bridge packets when the non-root bridge is associated to a root bridge with WPA-PSK configured.

•CSCed94862—Bridge does not forward SSTP message when Spanning Tree Protocol is disabled.

•CSCed86456—TKIP/WPA has no replay detection for links with concatenation enabled.

Workaround: Use CKIP (Cisco's proprietary TKIP) when using concatenation. This mode offers the best combination of security and throughput performance for bridges. If TKIP must be used, disable concatenation, but with reduced throughput performance.

•CSCee18627—If the access point/bridge is not configured as a local authenticator, the access point/bridge reboots when you enter the clear radius local-server useruser command.

•CSCed59485—SSH is still enabled after user disables it and reboots.

Workaround: disable SSH from the CLI by issuing the following commands:

–crypto key zerosize rsa (answer yes to remove all rsa keys).

–no ip domain-name (domain-name)

•CSC in64553—Tracebacks received and TACACS+ authentication fails when DHCP is selected.

Workaround: Assign a static IP address instead of DHCP when using TACACS+.

•CSCed50298—Inconsistent association table before and after changing modes from non-root bridge to workgroup bridge.

•CSCin72424—350 bridge fails to associate to a remote bridge in WPA Migration Mode.

•CSCed84862—Failure to configure MAC authentication server via WDS when local MAC is configured.

Resolved Caveats

These caveats are resolved in Cisco IOS Release 12.2(15)JA for the 1310 access point/bridge:

•CSCec16481

A Cisco device running Internetwork Operating System (IOS) and enabled for the Open Shortest Path First (OSPF) Protocol is vulnerable to a Denial of Service (DoS) attack from a malformed OSPF packet. The OSPF protocol is not enabled by default.

The vulnerability is only present in IOS release trains based on 12.0S, 12.2, and 12.3. Releases based on 12.0, 12.1 mainlines and all IOS images prior to 12.0 are not affected. Refer to the Security Advisory for a complete list of affected release trains.
